From: Zhang Chen <zhangchen.f...@cn.fujitsu.com> In this unit test we will test the mirror function.
start qemu with: -netdev socket,id=qtest-bn0,fd=sockfd -device e1000,netdev=qtest-bn0,id=qtest-e0 -chardev socket,id=mirror0,path=/tmp/filter-mirror-test.sock,server,nowait -object filter-mirror,id=qtest-f0,netdev=qtest-bn0,queue=tx,outdev=mirror0 We inject packet through socket netdev(qtest-bn0), filter-mirror(qtest-f0) will mirror the packet to chardev mirror0. Then we try read packet from mirror0 and then compare it with what we've injected.
